, TO ALL WHOM IT MAY CONCERN: p Be it known'that I, SAMUEL ROOKAFELLDW, of Muscatine, in the county'of Muscatine, and State of Iowa, i vhaveinventcd a new and useful Improvement in Mowers and Reapers; and I do hereby declare that the following'is a full, clear, and exact desorption of the construction and operation of the some, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a plan view of thesaid improved machine,

Figure 2 a sectional side elevation, and I Figure 3 a representation of the double-hinge connecting-links and lever for elevating the cutter-bar Like letters of reference indicating the some parts whenin the different figures;

The object of'my improvement is to afford better facilities to the operator for guiding and controlling the. cutter-bar during the operation of the machine; and my invention consists in the peculiar construction. and k application of a. double hinge for connecting the cutter-.barto the frame-of the machine, in combination with links, cranks, and levers, for operating the said her, substantially as hereinafter specified.

, Referring to thejdrawings, A is the frame of the machine; 13, the cu-tter-bar; O, the side-delivery dropper; D, the driver's s'eatg E, the tongue; F, the'double-tree; G the double hinge; g", the links, and g" the crank for connecting and elevating the outer'cnd of the cutterbar. I

The frame -A is supported upon an axle and two wheels inthe usual manner. The cutter-bar B is connected to the rear end of the frame A by means of the double hinge G, which is a block of metal connecting. the frame A and cutter-bar 13 together by two pivots at right angles to each othcr,as shown in fig. 3, and permits the said cutter-bar to be readily elevated at its outer end as-occasion may require, and also as readily @to permit the points of the fingers of the said bar to. elevated as occasion may require.

These movements of the bar B are efi'ectcdhy means of the-links g, criink 'g, and a hand or foot-lever, H, within reach from the drivers seat D to elevate the outer end ofthe said cutter-bar B, and, by means of the hand lever I, which is jointed to "the projecting inner shoe 6' of the said cutter-bar B, to eleyate the points of the fingers of the same, in either case the said her D turning freely on-the douhlc-hingejoint G..

The said delivery-dropper C consists of ascrie's of light, thin slots, 0, projecting from a head-piece, c, which is pivoted to the rear end of the slide or shoe I). of the cutter-bar B, so 'that it will swing horizontally on its pivot. The free ends of the said slats rest upon a supporting-bar, b", which extends horizontally back from the outer end of the cutter-bard (s'ee fig. 1,) and the said droppcrC is operated or swung horizontally inward, and also outward to a right angle with the cutter-bar B, (as indicated by the dotted lines v-o infig, 1;), by means of the hand or foot-lever K, and connecting-bar It. i i

The drivers seat D is supported over the middle of the frame A, and therefore centrally in rear of the draught-animals, by means of the supports d (1 attached to a sheet-metal cap, (1, which fits over the master-cog wheel L, and thus protects the driver's feet and the driving-reins from becoming caught by the master-wheel; and also aiiords the best positionfor guiding the team. t

The tongueE has its innerend pivoted at. e, so as to allow of its free movement thereon in u'vertico plane, and fixed to the upper side of the said inner end there is an extension, 'e, which serves 'as a lever-arm whereby the driver in the seat D can placc'his foot, and thus press down the forward part of the frame A, and consequently elevate the rear part of the same, asindicated by the dotted lines in fig. 2, and secure this canted position by means of a pin in'thc rack-bar e', the double-tree F being attached to the framerA, and therefore beingbelow and free from the said tongue, the casting forward of the said frame does not increase the weight 1 on the draught-animals, nor interfere with the progress of the machine. I

In operating the side-delivery dropper C, after thegrain has fallen back upon it, the driver, by means of the connecting-lever K, swings the said dropper horizontally outward to about a right angle with the cutter-liar B,

as indicated by the dotted lines in fig. 1, and letting it drop, the stubble passes upbetween the slats G into contact with the gavel, and thus,i n'connection with-the advancing sliding motion of the said dropper C, the

' secure By Letters Patent, is-

gavel is left behind, when, by a reversed motidn, given by the driver to the lever K, the dropper is swung back into placeas before. As the grain will c ontinue to heart, and to fall back whilst the dropper is in its outward positib n, it is intended that a curved arm or her, not shown in the drawing, shall he applied, and caused to fall or swing, so that it willreceive and support this falling grain, whilst the dropper is swung outward, and rise or swing out so as to let the grain fall upon the dropper immediately o n its (the lntters) return in place.

The operation of the other devics'havirig been fully explained, what I claim as, my invention, and desire to The double hihge G, cbnstructed substantially a s described, in combination with the frame A, cutterbar 1),

links g, qrank g", and levers H and I, the said parts being arranged to operate substantially a}; and-for the purpose described.
